北京帝豪大厦分户计量采暖与换热站设计
摘要
随着现代生活水平的提高,人们对热能的需求越来越高。将自然界的能源直接或间接的转化成为热能,以满足人们需要的科学技术,称为热能工程。采暖就是用人工的方法向室内供给热量,使保持一定的室内温度,以满足人们对室内条件和工作条件的要求。所有供暖系统都由热媒制备(热源)、热媒输送和热媒利用(散热设备)三个主要部分组成。
本设计主要采用分区供热和分户计量采暖系统,热源由地下一层的换热站集中供给,散热器给室内的供热方式由对流供热和辐射供热。根据此建筑物的特点采用分区供热,以防止压力过大而超过底层散热器设备的允许值。散热器采用下供下回的连接方式,管道敷设在垫层内,使室内布置更加合理、美观。采暖室内系统采用双管同程式,此系统的好处是可以避免水平方向的水平失调,即不至于使距干管最远用户无法达到要求的温度。供热中干管系统采用单管异程式,这样可以节约管材,减少占地面积。同时在各个用户的入口都有热计量表,用户就可以根据自己的需要来调节热量,这样既满足了人们对生活条件的需要,又符合了经济、节能等方面的要求。

The Design of Household-based Heating Metering and Heat Exchanger station for Beijing’s DiHao Apartment Buildings
Abstract
With modern improvement of living standards, people's growing demand for high heat. Heating is to use artificial methods to the indoor heat supply, maintaining a certain level of the indoor temperature to meet the people's indoor and working conditions demands. All heating systems by the heat of the media (heat), heat-borne transmission and use of heat medium (cooling equipment) of three ponents.
The main design and use of district heating household metering heating system, heat from the ground floor of a heat transfer station on supply, the indoor heating radiator to form by convection heating and heat radiation. According to the characteristics of buildings used district heating, in order to prevent excessive pressure on the bottom radiator equipment and over the allowable value. The next time a radiator for the connection, the laying of pipelines in the cushion, the interior layout more rational, attractive. Indoor heating system uses twin-tube with programs, this system has the advantage of avoiding the level of imbalance in the horizontal direction, that is not the farthest from the stem of the user can not meet the required temperature. Heating system in the trunk of different single program, this can save pipe, reduce floor space. At the same time in all users have the entranc
